Mara Laser is a business company that for 30 years and more has been analyzing, making and trading laser and GPS controlled levellers, calling on buyers in about 30 states all over the world.
Thanks to GPS and laser control technologies, we can get to outstanding results in many sectors of utility: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of returns and high capacity in various situations: from the machine operating speed regime, to a total affidability and assurance of the result.
The technology used by Mara is what makes it unique, and the results obtained all over the world testify this. Laser and GPS receiver technologies provide an unrivaled performance, mostly when they are used together.
Laser technology is applied to the levellers in a way that continually synchronize the height of the blade.
The leveller, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is placed on a tripod that sees the natural inclination of the soil and communicates the signal to the receiver, which is instead located on the machine itself.
The laser beam, for its own characteristics, enables very high accuracy even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, located on these machines, gives back an ideal pianification for the leveller to follow while operating.
The receiver also has an important role, because it correctly reads the laser light received from the transmitter, through special photodiodes. The receivers, made by Mara Laser, guarantee the levellers will be able to move on any kind of soil and receive the 360° signal, though it could be poor or it is subjected to interference.
On the leveller, moreover, there is a control system to annul external interference. It lowers wind sound, automatically reaches the signal and sets the power of the tractor.
GPS receiver technology
GPS technology, after all, is used to set the position of the leveller and the height of the blade.
The levellers, that implement this technology, get the laser signal from the satellites: even in this situation the pianification is represented by the signal and reproduced on the soil.
Nowadays, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been obtained, even though this technology offers minor accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the minor accuracy is compensated by the wide elasticity of use, mostly when this technology is used to work on large land portions with various inclinations, such as agricoltural ground and building constructions.
Integrated laser + GPS system
Mara Laser has created and made an integrated system that matches the precision of laser technology with the potential of GPS, suitable for harsh soil.
The higher accuracy of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Hence, the Mara system can set the height of the tractor leveller and the place of the blade itself.
The creation of the 3D map of the soil enables to highlight the land portions that has to be scraped, the loading areas, the starting point, and the best route that enables to make the best work possible, with both the tractor and the leveller in the right position.
Hence, the operator will have instant instructions through the constant updating of the data by the system.
Fields of application
The outstanding accuracy and elasticity of the levellers made by Mara Laser assure their use in various fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many benefits assure a important increase of the arable land portions. They enable a reduction in the amount of water used, they can provide more abundant harvest, a less use of chemicals, as well as seeds. The decrease in work times, furthermore, makes the use of these machines a sure investment.
- Laser levelling machines for construction:
Mara Laser gives a perfect precision to obtain ground floors with very reduced deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, be filled with concrete. The decrease of work times and the possibility of obtaining a perfect inclinatoin for water to flow down, are other benefits that make these machines worthy and priceless in this fields.
- Laser levelling machines for earth-moving:
the fine performance of the Mara levellers enables to move large quantity of soil very quickly and with low power. In this way, shorter work times, lower costs and greater accuracy in creating the horizontal plan and inclination, are achieved.
- Laser levelling machine for sportsground:
this type of technology can be utilized very well in this field as it enables to level even existing sectors, repairing slope without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the accuracy, reduced size and easy handling of Mara levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right inclination and also a fabulous aesthetic result are ensured.
- Laser grader machines for roads:
in this field, important results are achieved thanks to the skills of the Mara’s laser graders to perform the same job as the motor grader, with minor costs and more convenient times. In addition, there are important benefits, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
